So I haven't tested the fan, because it's all done a way and I can't seem to find where the fan is plugged into.

Though my side case fan I had off for awhile, just plugged it back in to put the side door on, and it isn't spinning. There are only 2 spots to plug in a fan as far as I can see, so I test the other port and it's still not spinning.

So, would that indicate a problem with the motherboard, or could that still be the two fans now? They are old enough I suppose.

I just don't want to go by some fans, and have them still not work. Anyway I can test it...
